Application med February 12, 1917, serial No. 148,004.

To all whom t may concern:

Be itknown that I, WILLIAM R. FINLAY,

a citizen of the United States, residing in the city and county of San Francisco andl State, of California, have invented certain? new and useful Improvements in Demountable Rims, of which the following is a specifcation.

The hereinafter described invention relates to a demountable rim for the attachment of solid tires to the ordinary rim.

adapted for the reception of pneumatic tires, whereby the rim now in use may be employed for the reception of the present invention without changes or alteration being made p.

therein. f The invention is especially designed fo applying solid tires to, the wheels of motor driven delivery vehicles, to trailers usually associiated with motor vehicles for the deliverv o invention is the production of a rim carrying a solid tire which may be quickly and easily applied to the rim of anl ordinary wheel for automobiles and trailers and this without changing or varying the construcf tion of the r1m mounting for said wheels,-

the construction of the demountable rim carrying the solid tire being such as to permit of being applied to the rim of the wheel and securely held thereto without the utilization of means for bolting or fastening the same to the wheel structure, as is usually the i case in applying a demountable rim to theA wheel structure.

To comprehend the invention, referenceshould be had to the accompanying sheet of drawings, wherein- Figure l is a broken part sectional side elevation of an ordinary clencher rim withl the solid tired demountable rim applied thereto.- Y Y, Fig. 2 is a transverse sectional elevatlon Ataken on the line 2-2 Fig.v 1 of thel draw'- ings and viewed in the directionv of the'V arfv IOWS.

In the drawings, the numeral 1 designatesl the wooden felly of an ordinary 'automobile` wheel carrying a clencher rim 2. .In thel application of the invention to this type of rimmed wheel, a segmental illerblock 3fisk inserted circumferentially of the rim 2, so as to'close the space and produce a circumferential bearing surface 3' intermedlate ,the

goods, and equally so to the lighterl types 0I auto-trucks, and the object of the ber 7 which projects beyond the under surface of' the flange 4 so as to partly embrace f the outer wall member 4 of the rim 2, which saidv rim is attached to the felly l in the usual manner. The opposing wall member 6 of the bodymember 5 of the demountable rim is bent backwardly upon itself to pro-A vide a return flange member 7', which terminates in an outwardly projected lock ange member 8 lying at substantially riht an es tothe member 7 The flange mem er 8 1s provided at intervals throughout its circumferencewith bolt openings 9, through which are passed securing bolts 10 for unit- Ing the same to the circumferential angle lplate l1, which constitutes the lock `ring member for the demountable rim, the inner flange wall thereof embracing the inner wall member 4 of the clencher rim 2. The bolts l0 pass through bolt openings formed in the 'lock ring 11 and are secured in place by nuts 12 screwed thereon and held against working loose by the cotter pins 13.

Within the demountable rim is situated the anchor or anchor plate 14, preferably shaped as shown in Fig. 2 of the drawings,

to which is molded or otherwise connected the solid rubber or composition tire 15, which with its anchor or anchor plate 14 is fitted to the demountable rim in `any suitable manner to be-partly embraced by and held between the side. flanged wall members 6 and 6 of the said rim.

rIn tting the demountable rim with its solidtire 15 to the rim2, the said rim is slipped over the fixed rim v`2 and the filler block k3 untilthe inner wall of the 'fiange member 7 A of the demountable rim bears firmly against the outer face of the member 4 of the rim 2. The lock ring angle member .11 yis then positioned to bear against the outer surfaceof the side wall member 4 of the iixed rim 2 and the under surface -of'the flange member 8 of the demountable rim, when the bolts 10 are inserted and the parts tightened by the application of the nuts l2 to the fastening bolts. The tightening of the bolts 10 draws the lock ring angle member securely in place against the wall member 4 of the fixed rim 2 and thus firmly attaches the demountable rim with its solid tire l5 to the wheel to b`e tired.

In order to remove the demountable rim it is only required to disconnect the lock ring angle member 11, when the rim is free to be slipped from off of the wheel.

It is thus apparent from the foregoing that no fastening means are employed which are required to connect with the wheel structure or the rim member held thereto, hence the demountable rim with its solid tire is adapted for attachment to any of theordinary wheels designed for vehicles employing demountable rim structures.

The described demountable rim may be attached to and detached from a wheel member quickly and within a comparatively short time, inasmuch as only such time is required as is necessary to bolt or release the lock ring member ll relative to the flanged lock member 8 of the demountable rim.

The invention readily lends itself to the equipping of motor driven delivery wagons,

railers and light trucks with solid resilient tires, providing, as it does, an eiiicient, simple, and quickly demountable attachment capable of use without the employment of specially designed wheels for receiving the same.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is A solid tire carrying demountable rim for positioning over a clencher rim when the tire is removed therefrom comprising an annular body portion provided at its opposite side edges with integral parallel spaced pey ripheral tire retaining ianges arranged at right angles to the body portion, one of said flanges being provided with an integral extension lying substantially parallel with the outer surface of its coperating flange and at right angles inwardly relatively to said body portion forengaging onel side of said clencher rim to limit the movement of said demountable rim thereover, and the other of said flanges provided with. an outwardly eX- tended portion lying at substantially right angles to its coperating flange, an angular locking member for engaging the inner 'peripheral surface of said outwardly extended portion and for contacting with the side of' name to this specication 'in the presence of' two subscribing witnessesf LAM R.
